The cfKapture™ 21 kit is a magnetic bead-based DNA extraction kit designed to isolate circulating cell free DNA (cfDNA) from human plasma and serum. The cfKapture™ 21 kit is uniquely equipped with a plasma stabilization buffer; SE buffer allows plasma sample to be stabilized during storage or transport for up to 21 days at room temperature when mixed with plasma sample. This functionality offers processing laboratories time flexibility for optimizing their operational efficiency as well as outreach for receiving samples at local and international levels. The isolated cfDNA can be directly used for real time-PCR and DNA library preparation suitable for next generation sequencing.
